No Support for 3.3V

The pcic nexus driver for the PCMCIA interface does not support 3.3V on devices. Cards that are 3.3V only do not work correctly; they seem to hang a system. There are several related causes for this problem:

The pcic driver cannot determine if it is a 3.3V only card (needs to read this information from the bus bridge and refuse to set 5V)

The pcic driver cannot specify that 3.3V is needed

Some of the new PC cards are now available as 3.3V only. This includes variations of supported devices such as PC ATA and SRAM. New bus bridges, such as the TI PCI1130/1131, support 3.3V as well as 5V.
